WHAT ARE THE ADVANTAGES AND DISADVANTAGES OF CATEGORY 4 SUNGLASSES?

Among the various levels of protection available in sunglass lenses, category 4 sunglasses guarantee the greatest protection against harmful radiation. Under certain circumstances, they are the best option, although in other situations, their use is completely inadvisable. But in what specific scenarios is it advisable to opt for this option, and in what other situations would it be wise to avoid using them?

Extreme conditions in which its use is recommended

By absorbing between 92% and 98% of harmful light waves, it's an ideal choice when outdoor conditions are extreme. So, if you're planning to engage in any activity in high mountains or offshore during periods when the Sun is close to our planet, you'd be wise to choose a model with these features.

This way, you'll not only prevent eye problems, but also avoid annoying reflections that occur on surfaces like water or snow. To maximize their performance, it's also a good idea to opt for lenses mounted on white frames that reflect light beams.

Driving with this type of protection is not a good practice.

That said, it's essential to consider other situations in which the use of category 4 glasses should be completely ruled out. These include driving any vehicle, as specified by the DGT itself, which even warns of the possibility of being fined if we violate these guidelines.

Instead, it's recommended to protect your eyes with lenses with a sun filter of 3, capable of blocking between 81% and 91% of ultraviolet rays. Although the use of lower protections is also acceptable, it's important to consider the intensity of the radiation at any given time. Type 2 lenses capture between 57% and 81% of harmful waves, type 1 lenses capture between 20% and 56%, and type 0 lenses capture a maximum of 19%.

Category 4 models from AWA Sunglasses: comfort and style on the high seas and in the high mountains

Of course, if you plan to go mountain biking, skiing, sailing, or any other water activity away from the coast, you'd be wise to take care of your eye health by using category 4 lenses. Even on the sunniest days, you can enjoy your favorite activities without worry or discomfort from light reflections off the snow and water.

The first step is to choose the AWA Sunglasses model, preferably with white frames, that best suits your circumstances. For round and oval facial shapes, the slightly angular contour of the Tulum is a perfect fit. The attractive design of the Somo, also dominated by straight lines, is another successful choice for these types of faces.

Something similar happens with the Mundaka, which are also an ideal choice for heart-shaped faces. Since they barely reach the cheekbones, their low height achieves optimal balance for the features. Finally, the versatility of the Xagó is fully compatible with almost all body shapes, whether we're talking square, rectangular, oval, trapezoid, triangular, diamond, or heart-shaped.
